As Japan’s space agency prepares for its first moon landing early Saturday, it’s aiming to hit a very small target.
The Smart Lander for Investigating Moon, or SLIM, is a lightweight spacecraft about the size of a passenger vehicle. It’s using “pinpoint landing” technology that promises far greater control than any previous moon landing.
While most previous probes have used landing zones about 10 kilometers (six miles) wide, SLIM is aiming at a target of just 100 meters (330 feet).
